葡萄糖氧化电极过程的研究
|
摘要
以葡萄糖和溴化锌为反应物,以铂电极、玻碳电极为工作电极,用循环伏安法测定了葡萄糖氧化的电极过程,研究了电极材料、反应物浓度和扫描速度对氧化过程的影响。结果表明:铂电极比玻碳电极好;比较好的溶液组成是10%的葡萄糖和3%的溴化锌,电化学反应的电流比较大; ip与v1/2成正比关系,该氧化反应是由扩散控制的。这些结果对研究葡萄糖酸锌的制备具有一定的参考价值。
The process of glucose oxidation electrode by cyclic voltammetry was studied with glucose and zinc bromide as raw materials. The platinum electrode and glassy carbon electrode were used as working electrode. The effects of electrode materials,concentrations of reactants and scan rate on oxidation process were investigated. The results showed that platinum electrode was better than glassy carbon electrode. The 10% glucose and 3% zinc bromide were good solution,and the current was high. The ipwas proportional to the square root of scanning rate,and the electrode process was a diffusion-controlled process. These results were helpful for the preparation of zinc gluconate.
